I updated the VMware version on a Dell T710 last night from 5.5 Update 2 to 6.0 Update 2. This morning I see a warning/alert on that ESXi host stating "Deprecated VMFS Volume(s) found on host. Please consider upgrading volumes(s) to the latest version.".

I recall during the update process there was a prompt stating that some of the volumes could not be updated related to VMFS. The consultant I worked with stated that the warning was probably due to the fact that the VMware update is being applied to an SD card and its not a big deal.

The resolution is to restart the management agents. My question is if I restart the management agents, will that take down the VM's that reside on that host? I want to say 'no' it will not; but, I want to make sure instead of guess at that.

Connect to the console of your ESXi host.
Press F2 to customize the system.
Log in as root.
Use the Up/Down arrows to navigate to Troubleshooting Options > Restart Management Agents.
Press Enter.
Press F11 to restart the services.
When the service restarts, press Enter.
Press Esc to log out.

But will this affect the production Virtual Servers on that host? Or will production not be affected?

1. There does not appear to be any mission critical VM's on that datastore.
a. Please see the screen shot below.

2. The MOGL-VCS is the old VCenter server that is going away soon.
a. It will be retired/removed in 2 weeks.
b. I am still using that VM as a printer server; but, it will go away after enough testing has happened.

3. The ISO folder just contains installation software.

4. MOGL-Linux is just used for a free web interface that allows for asset tracking.
a. I would like to move that actually.
b. I believe the only way to move this VM is to:
i. Power it off.
ii. Download the VM to my PC.
iii. Upload the VM to another datastore.
iv. Then right-click on the “.vmx” file and select “Add to inventory”.
c. The power on the copied VM.

4. If I remove or just simply allow the other files to stay in the datastore, will I still need to update the Datastore?
